This is how I think about suicide, when u kill yourself you do it to end whatever suffering you think you’re in but ask yourself “Am I going to a better place?” NO.
I will be headed to a much worse place with worse pain and unimaginable suffering, the loneliness and abandonment i felt in this world will be nothing compared to the loneliness, hopelessness and abandonment I’ll feel in the hereafter. It will be worse.

What is worse than being abandoned by your lord?

Your life is not yours to take, you didn’t bring yourself here. It’s a debt and the owner will come to take it when he deems the right time but rather live searching for the truth and dying upon it.

In my opinion, occupying yourself and freeing your mind from your negative and depressive thoughts helps a ton. I usually do that by immersing myself in a hobby. For me, I like to play and watch sports. When I’m depressed I’ll watch more games and play more pickup football and basketball. It’s a double positive because you occupy your mind with other non depressive thoughts and the endorphins you get from sports and exercise makes you feel good about yourself
